It looks like the original idea behind always doing a re-initialization of a removable SDIO card during system resume in mmc_sdio_resume(), is to try to play safe to detect whether the card has been removed. However, this seems like a really a bad idea as it will most likely screw things up, especially when the card is expected to remain powered on during system suspend by the SDIO func driver. Let's fix this, simply by trusting that the detect work checks if the card is alive and inserted, which is being scheduled at the PM_POST_SUSPEND notification anyway.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
